Search 10 U.S.C. § 332 : US Code - Section 332: Use of militia and armed forces to enforce Federal authority

Whenever the President considers that unlawful obstructions,
combinations, or assemblages, or rebellion against the authority of
the United States, make it impracticable to enforce the laws of the
United States in any State by the ordinary course of judicial
proceedings, he may call into Federal service such of the militia
of any State, and use such of the armed forces, as he considers
necessary to enforce those laws or to suppress the rebellion.
